This a.m. over breakfast I initially thought we were having a tremor. (I recall one centered in Annandale that I felt here in Springfield several years ago. ) Apparently, many concerned citizens voiced concerns to police and news organizations. The explanation I read on the WTOP website for the considerable distance of impact was the cloud layer and temperature profile of the atmosphere. Both combined to reflect/bounce the percussion along.

Did we ever! It shook our house and rattled the windows, and we're all the way out in Bristow. Our two-year-old's been talking about our shaky house all day.

We actually took a car ride this afternoon to try to identify the source, once my curiosity finally got the best of me. I thought maybe it was from a construction site not far from our neighborhood, but no dice, obviously. I'm glad to finally know what it was.

I'm on the Base close to the training, and yes, they're out there blowing stuff up.

Interesting--didn't hear a THING in Woodbridge, yet it could be heard in Springfield.
